Sorry for the delay. Automatic notifications on the blink again. PM me if there is a delay of say 24hours in me getting back to you.
Now, when you downloaded that MPass.exe and click on it, it should create and ISO which you can burn to a CD. Burn it to a cd as an ISO image. It's important you burn as an ISO. Burning the ISO image file to a CD or DVD is a bit different than just burning the file. You need to choose the "burn image" or "write image" option in your burning software and then choose the file.
Also sometimes the download can get corrupted and you have to download again. I think that one should be about 1.76mb.
Try again and tell me if you have further difficulty.
